The term "Shaman" is a commonly used term by anthropologists to refer to an individual who has acquired exceptional powers to deal with the supernatural. One usually becomes a shaman after being seized by spirits. The term originates from the Tungus people, reindeer herders of eastern Siberia. Many anthropologists use the term to describe the holy people of Native American cultures but many Native Americans dislike the term because it is of foreign origin and does not encompass the diversity of Native specialists. It is generally best to call these people "holy people" instead.
